Nemesis Electric Supercar: 330bhp Ecotricity Prototype

The Nemesis stands as a pioneering achievement in electric vehicle engineering, crafted by Ecotricity, the UK’s leading green energy provider. This one-of-a-kind supercar reimagines high-performance motoring with zero-emission power sourced entirely from wind turbines, challenging the notion that sustainable transport must compromise on excitement or speed.

Origins and Vision Behind the Build

Ecotricity’s founder, Dale Vince, envisioned a machine that would shatter stereotypes of electric cars as sluggish and unappealing. Starting with a used Lotus Exige chassis, his team of former motorsport engineers spent nearly two years gutting the original powertrain and integrating cutting-edge electric components. The result was the Nemesis, a vehicle designed not just for efficiency but to dominate tracks and roads with raw power and agility.

This project emerged in the early 2010s amid growing interest in electric mobility. Unlike mass-produced EVs, the Nemesis was a bespoke creation aimed at proving that renewables could fuel supercar-level performance. Vince’s goal was clear: create a ‘mad car’ capable of outpacing traditional petrol exotics while maintaining a pristine environmental footprint.

Engineering Marvel: Powertrain and Design

At the heart of the Nemesis are twin brushless electric motors, each delivering 125kW (168bhp), for a combined output of 330bhp. These rear-wheel-drive units produce a staggering 600Nm of torque available instantly from standstill, eliminating the need for multi-gear transmissions.

The power is routed through a two-stage belt-driven reduction transaxle, ensuring seamless acceleration without gear shifts. The battery pack comprises 96 lithium-polymer cobalt cells (100Ah, 4.2V each), totaling 36kWh capacity, integrated into a patent-pending Structural Energy Storage System (SESS) using double-skin carbon fiber and aluminum honeycomb for enhanced rigidity and safety.

Despite the added weight—kerb mass at 1,166kg, about 300kg more than a standard Exige—the Nemesis retains Lotus’s legendary handling DNA. Its body, restyled by McLaren F1 designer Peter Stevens, stretches 900mm longer than the donor car to accommodate the battery and provide extra cabin room, blending aggressive aerodynamics with futuristic appeal.

Performance Benchmarks and Records

The Nemesis delivers ferocious acceleration: 0-100mph in approximately 8.5 seconds, outpacing many contemporary supercars including some V12 Ferraris. Its top speed reaches 170mph, sustained by the electric motors’ consistent power delivery.

In 2012, the Nemesis claimed the UK land speed record for electric vehicles at 151mph, a testament to its engineering prowess. Drivers noted its jet-like whine and seamless thrust, making it feel exceptionally rapid on public roads despite the prototype nature.

Battery Range and Charging Capabilities

Real-world range varies from 100 to 150 miles based on driving style, ideal for spirited weekend drives or track days. Aggressive acceleration reduces this figure, but conservative use extends usability.

• Fast Charge: Under 2 hours from empty using a 64A three-phase supply or optional rapid charger.
• Standard Charge: 8-9 hours via 240V 13A household socket.
• Innovative Feature: Retractable charging cables hidden in the rear for convenience.

Exclusively charged with Ecotricity’s wind-generated electricity from 51 UK windmills, it achieves true zero-CO2 emissions, a key differentiator from grid-powered EVs.

Driving Dynamics and Unique Sensations

Behind the wheel, the Nemesis offers instant torque for explosive launches and a high-pitched electric whine reminiscent of a fighter jet or racing transmission. Handling remains sharp, benefiting from the low center of gravity provided by the battery placement.

Reviewers praised its balance: brisk yet composed, with promise for further tuning. The absence of gear changes provides uninterrupted acceleration to redline speeds, while the added length improves stability without sacrificing agility.

Eco-Credentials and Broader Impact

Powered solely by renewables, the Nemesis exemplifies sustainable high-performance. Ecotricity’s network ensures green charging, aligning with the company’s mission to expand wind energy adoption. This project influenced early EV infrastructure, including the Electric Highway network.

By demonstrating that EVs could rival supercars, it paved the way for modern electric hypercars, proving battery tech’s viability for speed and fun.

Challenges and Limitations

As a prototype, the Nemesis faced hurdles like limited range for long trips and dependency on specific charging. Finding wind-powered outlets en route could complicate zero-emission claims. Nonetheless, its 100-150 mile capability suited its role as a thrilling ‘weekend toy.’

Legacy in the EV Revolution

The Nemesis predated today’s EV boom, setting benchmarks for power, speed, and green integration. Its UK record stood as inspiration, showing entrepreneurs like Vince could disrupt automotive norms with renewables.

Though a one-off, it highlighted potential for lightweight, high-output EVs based on proven chassis like Lotus.

Technical Specifications Overview

Comparing Nemesis to Contemporaries

In its era, the Nemesis outperformed the Tesla Roadster in top speed and torque while matching acceleration. Against petrol Lotus Exiges, it traded some weight for silent, instant power.

Future Prospects for Similar Projects

The Nemesis’s success underscores demand for eco-supercars. Modern equivalents like the Lotus Evija build on such foundations, integrating advanced batteries and aerodynamics for even greater feats.
